In Parsha Haazinu Moses recites the song he scribed in the previous portion. He knows his life and his life’s work is at an end and as a parting song Moses recites words that act as an indictment of the ancient Hebrew’s sins, words that foretell punishment for future sins, and words that reassure them of Hashem’s love and redemption.

Why a song after writing down the Torah? Simple, literacy was not as prevalent then as it is today and lyrics have a way of burrowing themselves deep into the conscious mind. I often wake up humming a tune I heard the previous night or quietly sing to myself the same verse of a song over and over again throughout the day. Whether one finds having a song stuck on repeat in his/her head as annoying or not the fact he/she is conscious of those words and their meaning is important.
